Insufficient water supply leads to plant productivity decline and destruction. Along with this situation, instrumental methods of evaluation of water supply of plants are almost not used. An investigation connected with computer-managed systems creation and accumulation of data about plant vegetation process is carried out. The aim of the research is development of automatic agronomic complexes with computer management and yield formation. Measurement of leaf blade and evaluation of water deficit of plant before total fading is suggested to be done. The scheme of measurement of leaf blade hardness is presented. The scheme of electrodynamic transducer connection and measurement of leaf hardness with the help of balancing resistor is displayed. Transmission coefficient of auto-connected transformer is 1:2. Kinetics of change of leaf blade hardness of barley during creation of water deficit and after normal water supply reconstruction is compare and analyzed. The method of evaluation of water supply of plants, offered in the article, can be used for the creation of control sensor destined to plant water supply management.
